SPECIFICATION forming part of Letters Patent No.` 611,591, datedSeptember 27, 1898.

Application filed December 10,1896. p Serial No. 615,190, (No model.)

To @ZZ whom it may concern:

Be it known that I, HERMAN OASLER, a citizen of the United States,residing at Canastota, in the county of Madison and State of New York,have invented certain new and useful Improvements in Consecutive-ViewApparatus, (Oase No. 8 g) and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates generally to movingpicture or consecutive-viewapparatus, and particularly to the film or strip feeding mechanism ofsuch apparatus; and my invention consists in the novel construction ofsuch feeding mechanism whereby the speed of the winding-up reel isautomatically adjusted so as to correspond exactly to the speed at whichthe film is fed through the field of the apparatus without puttingsevere stress upon the film, in the means employed for facilitating theremoval from the reels of rolls of film or the placing of such rolls offilm thereon, and in the combination and relative arrangement of theparts.

The objects of my invention are, first, to provide an improved film orpicture-strip feeding mechanism for consecutive-view apparatus arrangedto Wind up the film upon a suitable reel, after it has passed throughthe field of the apparatus, at such speed that all slack shall be takenup and which shall not subject the film or strip to severe strain;second, to provide means for facilitating the removal of rolls of filmfrom the reels or the placing of such rolls on the reels Withoutunwinding the rolls, and, third, to make the whole apparatus simple,compact, and capable of operating at a high rate of speed withoutvibration and without injuring the film. These objects are attained inthe film or strip feeding mechanism herein described and illustrated inthe drawings which accompany and form a part of this application, inwhich the same reference-numerals indicate the same or correspondingparts, and in which- Figure l is a side elevation of the film or stripfeeding mechanism of a consecutiveview apparatus, together with thesupply and winding-up reels. Fig. 2 is a similar elevation of theopposite side of the machine, showing the variable-speed gears whichdrive the main feeding and the winding-up mechanisms and thefriction-brake which retards the feeding of the lm from the supply-roll.Fig. 3 is a detail side elevation of the upper portion of the feedingmechanism, showing the main feeding mechanism open for the threading ofthe strip. Fig. 4 is a detail plan view of the gripping-roller of theauxiliary feeding mechanism, the friction-disk 35, and the parts inproximity thereto. Fig. 5 is a detail plan View of the gearing at thetop of the driving-shaft of the main feeding mechanism,

Fig. 6 is a detail plan view of the regulatingshaft44:,which controls the speed of the main feeding mechanism, with theparts thereon, certain of these parts being shown in section. Fig. 7 isa detail `view of the variable-speed gear which drives the winding-upreel, showing the use of a spring to reinforce the weight of theworm-shaft in regulating the speed of the winding-up roll. Fig. 8 is adetail elevation of the reel upon which the stripis Wound. Fig. 9 is atransverse section of the same. Fig. 10 is a front elevation of thereel, with the surrounding band 25, this band being broken away fromabout the center of the figure to the top thereof and Fig. 11 is aperspective elevation of this band 25, showing particularly theprojections by which it is held to the reel when in use.

In the drawings the film-feeding mechanism is shown applied to aconsecutive-viewprojecting apparatus. The feeding mechanism consists ofa main feeding or delivering mechanism which draws the film 7 from thesupply-reel S and delivers it to the eld of the projecting apparatus, atake-up mechanism which carries the film from the field of theprojecting apparatus and delivers it to the Winding-up reel 24, and anauxiliary intermittentlyacting feeding mechanism which draws the filmintermittently through the fieldof the projecting apparatus.

The main feeding and the take-up mechanisms consist each of a series ofpulleys, about which runs a single feed-belt 21..

11, 13, and 38 are the pulleys which con- ICO stitute, with the portionof the feed-belt 21 upon them at any instant, the main feedingmechanism, and 49, 19, and 20, with the portion of the belt 21 upon themat any instant, constitute the take-up mechanism.

46 and 48 are idler-pulleys, and 47 isa belttightener pulley mountedupon a swinging hanger.

The belt 21 passes in a tortuous course around the pulley 11, over thepulley 13, and under the pulley 38, and then over pulleys 46 and 48,under pulley 49, and over pulleys 19 and 2O and the tightener-pulley 47.The pulley 38 is the pulley which drives the belt 21. It is mounted uponthe shaft 39, the end of which is seen in Fig. 2, and which is driven bya variable-speed driving-gear composed of a worm-wheel 40, a worm 33,mounted upon the shaft 41 and connected to said shaft by a spline, sothat the shaft may move up and down freely, and a friction-wheel 42,also mounted upon said shaft and coacting with the friction-disk 35,which is mounted upon the main driving-shaft 2 (shown in Fig. 1 and indotted lines in Fig. 4) and is driven by a belt 36, running over abelt-pulley 55, Fig. 4, mounted on said shaft, and over an idler 37.

The upper bearing of the shaft 41 is in a universal-joint bracket 54,(shown in Fig. 5,) and the lower bearing of the shaft is in a sleeve 43,secured against longitudinal movement relative to said shaft andlongitudinally movable in a bearing in a sleeve 56, (shown particularlyin Fig. 6,) mounted upon the shaft 44.

The sleeve 43 is provided with rack-teeth, and the shaft 44 has a pinion45, which meshes with these rack-teeth. The shaft 44 is Aalso providedwith a handle or crank (shown in Figs. 1 and 3) by which it may berotated. Rotation of the shaft 44 moves the shaft 41 and friction-wheel42 up or down, thus varying the distance of the friction-wheel 42 fromthe center of the friction-disk 35, and so regulating the speed of thepulley 38 and belt 21.

The auxiliary intermittently-acting feeding mechanism consists of twoopposing pulleys 3 and 4, (shown in Fig. 1,) driven at the sameperipheral speed by a belt 5, which also passes around a belt-tightener6. Pulley 3 is upon the main driving-shaft 2 and has a portion of itsperiphery of such diameter that when that portion is in proximity to thepulley 4 the film-strip between these pulleys is pressed tightly againstthe pulley 4; but a large portion of the periphery of pulley 3 is of asmaller diameter or is cut away, and when this portion of the pulley isadjacent to the pulley 4 the film is free.

The parts of the apparatus thus far described are also illustrated anddescribed and are claimed in a separate application, filed December 10,1896, Serial No. 615,189.

The strip or film 7 as it is drawn from the supply-roll 8 passes overguide-pulleys 9 and 10, over pulley 11 and the belt 21, thence aroundthe guide-pulley 12 and over pulley 13, passing under the belt 21, andthence around the stud 14 and through a guide 15, which guides it whilepassing through the field of the projecting apparatus and by frictionretards it sufficiently to hold it stationary when the auxiliary feedingmechanism is not feeding it forward, and between the pulleys 3 and 4 ofthe auxiliary feeding mechanism and bya loop through the guide 18 andaround pulleys 19 and 20, passing first under the belt 2l and then overit, around the guide-pulley 22, and through a guide23 to the windingreel24. In passing through the main feeding and the take-up mechanism it isbrought into close contact with the driving-belt 21 and is thereforedrawn from the reel 8 and taken up after passing through the field ofthe apparatus by friction with this driving-belt. The object of feedingthe film by a belt and not by pulleys driven by gearing or belting whichdoes not come in contact with the film is to avoid the unequal feedingof the strip in the main feeding and in the take-up mechanisms whichresults from the practical difficultyin making two feeding-rolls ofprecisely the same size and in driving them at precisely the sameperipheral speed.

The illuminating apparatus is designed to be placed upon the shelf 17.It is not illustrated in the drawings, as it forms no portion of theinvention.

16 is the barrel of the projecting apparatus.

The pulley 11 of the main feeding mechanism is mounted upon a swinginghanger and is arranged to be moved upward in the position shown in Fig.3, so as to slack the belt 21 and permit the direct threading of thefilm. The pulley 19 is also mounted upon a similarhanger. (Shown indotted lines in Fig. 1.) Inv threading the film it is carried from thereel 8 over guide-pulleys 9 and 10 and then between the pulleys 11 and13, pulley l1 being in the position shown in Fig. 3, a loop being formedbehind the pulley 13. This loop is then carried down and over theguidepulley 12. The film is then carried downward through the guidev 15,which is hinged and opens, as shown in Fig. 3, through the pulleys 3and4 of the auxiliary feeding mechanism and through the guide 18,between the pulleys 19 and 2O and over the guide-pulley 22 to the guide23 and to the winding-up reel 24. When the film has been threaded, thepulley 11 is restored to its normal position, (shown in Fig. V1,) thusdrawing the belt tight.

The winding-reel 24 is driven from the shaft 2 and friction-disk 35,mounted thereon, by means of the friction-wheel 34, mounted upon a shaft31, revolubly mounted and arranged to slide up and down in a sleeve Aworm 30 is rigidly secured to the end of this shaft and meshes with aworm-wheel 29 upon the shaft 28, upon which shaft the winding-up reel 24is mounted. When the friction-disk 35 rotates, this movement iscommunicated to the reel 24 through the shaft 31 and worm- IOO IIO

gear, the weight of the shaft 3l and parts thereon holding it atpractically its greatest distance from the center of the disk 35; butwhen the film 7 is drawn taut the reel 24 can rotate only at the speedat which the film is fed to it, and since when the friction-wheel 34 isat its greatest distance from the center of the disk 35 it tends torotate the reel 24 at a much greater speed than that at which the filmis fed by the feeding mechanism as soon as the film becomes taut thespeed of the film becomes less than the speed at which the wheel 34tends to drive it and the worm 30 climbs upon the gear 29, so raisingthe friction-wheel 34 until the speed of the windingreel is adj usted tothe speed at which the film is delivered to it by the take-offmechanism. As the film is wound upon the reel 24 the di ameter of thisreel gradually increases; but as it does so the shaft 3l graduallyrises, so as to keep the peripheral speed of the outside layer of filmupon the reel 24 the same as the speed at'which the film is delivered tothe reel. If theweight of the shaft 31 and parts thereon is notsufficient to balance to the proper degree the tendency of the worm 30to climb upward -upon the gear 29, the weight of thc shaft 3l and partsconnected therewith may be reinforced by a spring 57, as shown in Fig.7. The upper end of this spring may rest against the upper bearing ofthe shaft 3l, and the' lower end may rest against an adj ustable collar5S.

In order to provide a constant tension upon the film as it is drawn fromthe delivery-reel 8, a friction-pulley 5l, Fig. 2, is mounted upon thesame shaft which carries the reel 8, and a suitable friction-brake isapplied to this pulley. The frictionfbrake may be conveniently a band52, with aweight 53 depending therefrom.

The mode of operation of my invention is as follows: The variable-feedgear (illustrated and more fully described in another application filedof even date herewith, Serial No. 615,189) draws the web 7 from the reel8 as fast as it may be required, the necessary tension for smoothworking being secured by the band-brake 52. After passing through themachine the strip is wound up on the winding drum or rcel 24. It isevident that as the strip is wound up on this drum and the diameter ofthe outer circle increases the speed of rotation of the drum mustdecrease, so that the circumferential speed shall remain approximatelyuniform. My invention accomplishes this automatically by reason of thefact that the driving worm-shaft 31 is ordinarily held by its own weightand sometimes by the additional help of the elasticity of a spring, asshown in Fig. 7, in its lowest position on the friction-disk, as shownin the drawings; but when the worm-shaft is rotated by the friction-diskthe resistance to motion of the worm-wheel 29 causes the worm 30 tostart to screw up on the worm-wheel, thus raising the worm-shaft andcarrying the friction-wheel higher up on the friction-disk, and itsaction continues until the speed of the worm-shaft has become such as toput only the proper and predetermined amount of tension upon thestrip,which is winding up upon the reel mounted upon the shaft of theworm-wheel 2S, and it will appear that as the diameter of this reelgrows greater the friction-wheel 34 will be carried farther up upon thefriction-disk 35, thus reducing the angular velocity of the stripreeland maintaining the tension upon the strip practically uniform.

Itis frequently desirable after a strip of film has been wound upon oneof the reels 8 or 24 to remove the strip therefrom bodily withoutunwinding it and to place another strip thereon. In order that this maylbe done, one portion of the rim of the reel is hinged, as shown in Fig.8 and as also shown in connection with the reel 24 in Fig. l. Beinghinged, this section is capable of being swung inward, as shown in Fig.8 and in dotted lines in Fig. l, thus loosening the film somewhat.Preferably the film is not wound directly upon the reel, but upon acircular iieXible band or envelop 27, preferably of metal, which isslipped over the reel. The band 27 prevents the elasticity of the filmfrom taking up the slack which is produced when the hinged section ofthe rim of the reel is swung inward, as shown in Fig. 8.

.The band 27 is provided with projections 59,

which are adapted to enter slots between the body of the rim and thehinged section 25, so holding the band in place on the reel. The ends ofthe strip of metal which forms the band 27 overlap and are not rivetedtogether at the very end, so that a slot is left into which the end ofthe film, when folded over, may be placed, in order to hold it to theband. i A latch 26 is provided to hold the hinged section 25 of the rimof the reel in place when the reel is in use.

Various changes could be made in the details of my apparatus. Otherforms of variable-speed mechanism could be substituted for the frictiondisk and wheel, other locking devices might take the place of the latch26, other forms of friction-brake could be substituted for the band 52,and so on, as long as the principle of operation above described isretained.

Having therefore described my invention, what I claim as new, and desireto protect by Letters Patent, is
